The warp and weft preparation process of the fire hose fabric layer is single yarn winding, splicing, twisting, and knitting.

1. Single yarn winding. The purchased single yarn goes through the winding process, and the capacity is increased. After removing the defects, it is beneficial to improve the quality and efficiency of subsequent processing.

2. Зшивання. The одинарна пряжа (нитка або коротке волокно) після обмотка is зрощення перед скручування. The warp and weft generally have 2 to 10 joint shares, and some special hoses can reach up to 15 shares. It is required that the strands cross and evenly wind on the surface of the bobbin, without overlapping, and the number of strands in the whole package is the the same.

3. Скруч. The процес of скручування the yarn into an appropriate degree of twist after plying is called twisting. after twisting, the strength of the yarn is improved, and the inner yarns are arranged tightly and neatly, which is conducive to the subsequent process. The twist direction is divided into S and Z. The twist of ply yarn used for fire hose is generally 30-200 T·m{% 7b2}}. In the twisting process, attention must be paid to checking the running status of the feeding machine, end-break automatic stop device and tension device. Fire hose twisting equipment has a specially improved two-for-one twister.

4. Виробництво. Кручений уток іс перемотаний в a розмір той сірники розмір з круговий ткацький верстат човник, and the tube making process is suitable for subsequent circular weaving production. this process antly antly controls the winding regulator, automatic tube changing mechanism and end-break self-stop machine.
